Ogg Vorbis, typically known simply as Ogg, is a lossy format. Ogg is a container format, whereas Vorbis is the audio codec. To enable Max to generate Oggs, select the Ogg Vorbis checkbox under Formats in Max's preferences.
Configuring Ogg Vorbis Output
Ogg configuration is located in the Ogg Vorbis section of the preferences.
The lowest bitrate that Max can output for Ogg Vorbis without resampling the frequency is 48 kilobytes per second.
Quality
This is the recommended way to encode Ogg Vorbis files.To use the Quality setting, set the Target to Quality, then choose the desired quality setting. The settings are rather subjective, but 0 is roughly equivalent to a 64 kilobytes per second average, 5 to 160 kbps, and 10 to 400 kbps. Settings of 5-6 should produce CD-quality output.
Variable Bitrate
There are two ways to generate an Ogg file with a variable bitrate. One way is to choose a Quality setting which will maintain quality but with lower filesizes in subsequent updates to the Ogg Vorbis encoder; the other is to choose a Bitrate that you would like to be the average of the bitrate variation.
Bitrate
To set a specific variable bitrate average, set the Target to Bitrate, then choose the desired bitrate. Bitrates of 160 kilobytes per second and higher will result in CD-quality Oggs.
Constant Bitrate
Generating constant bitrate Ogg Vorbis files is not recommended.To generate an Ogg with a constant bitrate, set the Target to Bitrate, use the slider to choose the desired bitrate, then check Restrict encoder to constant bitrate.
